Value Collection 534132PR M8x1.25 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 534132PR is a metric flat socket cap screw manufactured from 12.9 grade alloy steel with a black oxide finish. The 90-degree flat head profile sits flush with or below the mating surface, making it well suited for assemblies where a low-profile or countersunk fastener is required. Drive engagement is through a 5 mm hex socket. The overall length is 70 mm and the thread is M8x1.25, partially threaded per DIN 7991. At a material grade of 12.9, this fastener delivers high tensile strength appropriate for demanding mechanical and industrial applications. Installation is performed by machinists, millwrights, or maintenance technicians working with metric fastener systems.

This screw is used in precision mechanical assemblies, machine frames, jigs, fixtures, and equipment enclosures where a flush or countersunk fastener is required. The partial threading allows the unthreaded shank to provide shear resistance in critical joint locations. The black oxide finish provides mild corrosion resistance and reduces light reflection in optical or sensitive environments. These screws are sold in a minimum order of 10 pieces, with a package quantity of 1 per unit.

Key Features

• 90-degree flat head seats flush in countersunk holes per DIN 7991
• 12.9 alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and low reflectivity
• 5 mm hex socket drive for positive torque engagement
• Partially threaded shank provides shear load capacity
• Metric thread standard: M8x1.25

Compatibility

Designed as an OEM-style replacement or standard-stock metric flat socket cap screw for equipment and assemblies requiring DIN 7991 countersunk hex socket fasteners in M8x1.25 thread size.

Installation Notes

Installation requires a 5 mm hex key or socket driver. Ensure the receiving hole is properly countersunk to 90 degrees to achieve full head seating. Verify mating thread condition before installation and apply appropriate thread lubricant or thread-locking compound per the assembly specification. Follow applicable machinery safety procedures and power down or de-energize equipment before working in areas where fastener access requires removal of guarding or covers.
